'American Hustle' may have gone down a storm with critics but its leading ladies took issues with certain aspects of the styling.

American Hustle, the latest movie from Silver Linings Playbook director David O. Russell, is quickly picking up speed before its big release this weekend with scores of gleaming reviews, a dazzling trailer, an enthralling promise and an inviting 1970s dresscode.

They May Look Comfortable & Carefree But 'American Hustle' Posed A Costume Challenge.

The movie follows Christian Bale's heavy and resentful Irv Rosenfeld, one of the most talented con artists in the world married to single mother Rosalyn Rosenfeld, played with emotional sincerity by Jennifer Lawrence. However, Irv is passionately in love with his mistress and business partner, Sydney Prosser, who is played by the ever brilliant and seductive Amy Adams.

The pair are recruited to work for FBI agent Richie DiMaso (Bradley Cooper), propelling them into the dangerous world of Jersey powerbrokers. However, as Rosalyn becomes more and more suspicious of her husband's extra-marital affairs, she is soon driven to extreme lengths to find out what's going on, and so threatens the stability of the entire operation.

In the movie, aesthetic is key to both building the characters' personalities and setting the extraordinarily bad-taste seventies scene. American Hustle revels "in its '70s milieu and in the eternal abrasion of sexy women and covetous men, American Hustle is an urban eruption of flat-out fun - the sharpest, most exhilarating comedy in years," writes TIME's Richard Corliss.

Whether it's the huge hair, massive glasses, ostentatious suits or skimpy disco dresses, there's no question as to which era Russell's film is set during. However, since the movie was filmed, the lead actresses have come forward in interviews to express their gripes regarding their rather challenging costumes.

Amy Adams, the "super-sexy Sydney Prosser, played with a gleam of pure self-harming passion," according to The Guardian, is clearly defined as a powerful, lioness of a woman who clearly feels completely at home with her overtly signalled sexuality. "I would not wear most of those clothes in real life," Adams told E! News, explaining the functionality problems: "There's just not enough double-sided tape to take me through my life as a mom with those V-necks."

Even The Guys Took Hours In Hair & Make-Up.

The actress and mother did admit that she temporarily enjoyed certain aspects of Sydney's dress, explaining, "It was really fun to wear and get to play a character who was empowered in those clothes." As most of her ensembles in the film are very revealing around the chest area, Adams admitted that a slip was pretty much inevitable: "You have to have a laissez-faire attitude about it," she smiled.

Similarly, Oscar-winning actress Jennifer Lawrence, described as "probably far too beautiful" to play Rosalyn, was forced to agree with Adams boob admissions. Telling MTV "I normally wear bras," Lawrence remembered her character's consistent lack of chest support: "I wouldn't say that it's ever exciting to see yourself without a bra in a dress that's three sizes too small for you."

Forbidden from underwiring due to the costume's period-appropriacy, Jennifer - like Amy - admitted that she had enjoyed the moment: "Exciting, I don't know," she said of going braless. "It was freeing." American Hustle will be released on the 20th December.
